Ammonium Nitrate (alias of 0222)

CAS RN:6484-52-2

Volatilization

The immediate loss of fertilizer nitrogen as nitrous oxide (biochemical & microbiological) into the atmosphere was determined by in situ measurements of the nitrous oxide evolution rates from uncultivated Eolian sand. The net loss was equivalent to 0.1% of the applied fertilizer for ammonium chloride, 0.05% for ammonium nitrate & 0.01% for sodium nitrate. The total immediate loss of nitrous oxide-nitrogen after application of mineral fertilizer is estimated to be 0.004-1.2 teragram/yr.
